Okay, so I listen well and am picking up my 35 lb Rocna this afternoon.
NEXT, the problem:

The sizing chart on the Rocna site

http://www.rocna.com/product-range/sizing-guides/?c=pounds

says this anchor is to be used with 5/16 chain and my chain/windlass are
1/4" high test.
So, I have the 5/16" shackle but am worried that I won't be able to attach
the anchor to my shackle.

Will it fit? Do I need to buy something to connect the 1/4" I have to the
new anchor?

I'm upgrading from a 25 lb plow.
What say the experts?

At anchor in Pensacola.

Snip:"...Look for the stainless steel shackles not the Cast ones. The pins
are smaller and the gap greater for the same strength..."

Stainless absolutely DOES NOT have the same strength as quality alloy steel
forged rated shackles specially those from "Crosby".  Google "Crosby"
shackles and find one with the certified load rating to match your rode.
These are used in hoist industry and load lifting around workers so are
rigorously tested to meet specifications. They give the diameters of all
shackles that are available galvanized. There is lot's of junk out there so
go with a "trusted" tested source when needing such a critical component.

Here's how I'd look at it: 1/4" High Test chain has a WLL of 2600 lb and the links have an inside diameter of .41 or .48 depending on whether the chain is made to NACM standards or ISO (ACCO) standards.
 
Regular strength 5/16" shackles have pins that are 3/8" in diameter= .37", so they would fit the chain. Trouble is their WLL is 1500 lbs.
 
High Test (alloy) 5/16" shackles also have pins that are 3/8" in diameter= .37", so they too will fit. Their WLL is 2500 lbs, close enough to the chain's WLL to be usable.
 
Another option is to put oversized links in the chain, using the largest rod that will fit through the link. 7/16" rod (.43") will fit NACM chain (.48"), but ISO chain will probably have to have its links widened that extra .02", not a problem for someone with a 5 lb sledge.
 
With oversized links, made to fit the shackle, 7/16" regular strength shackles (3000 lb WLL) can then be used. What's even nicer is that high strength (alloy) shackles can still be used, if you so desire, since the space between their eyes is essentially 1/2" (.5"). Oversized links allow the option to use either type of shackle, something that can prove helpful should you not be able to get one or the other in a timely manner.
 
As far as stainless steel shackles are concerned there are a few companies which make very good s/s shackles. But, I have two problems with s/s shackles. One, I've yet to locate any standards for the manufacture of s/s shackles, leaving the quality, strength, dimensions and testing up to the indivdual manufacturer. Two, although a shackle connecting the chain to an anchor is not known to be susceptable to galvanic corrosion, s/s is susceptable to pitting and crevice corrosion if in a low oxygen environment, such as slow moving water, polluted water or buried in the bottom. Because of this reason, s/s shackles and s/s oversized links may be a poor choice for long term anchoring  or long term moorings.

As usual, I am in need of some help.  I have a Frigidaire LC-248J-L5 (circa
1988) that will fill with water, agitate and drain but will not spin.
The only belt I see rotates during the agitate cycle.  I am presently on the
Lower Potomac River by the Chesapeake Bay in Lottsburg, Va. and there is
very little local service available. Any suggestions or direction will be appreciated.

Thanks in advance.

We're all set, and it's fabulous. I bought a Rocna 15 (33 pounds) and it is
amazing. We (that's the royal "we" meaning a local named Bill) removed the
old Davis 25, the u-bolt that no longer worked and installed the Rocna. Of
course this required a trip to West... because they sell my 1/4" high test,
we were able to check the shackles and the 3/8" fit (with a bit of
persuasion) so I've definitely upgraded.

There's a satisfaction in lowering the hook and KNOWING it's going to hold
the boat without nonsense. And like Rudy says, (paraphrased) "if it doesn't
make people laugh, it's too small" (I think I've got that covered now)

This afternoon I'm leaving for a day and without worry too -- the anchor is
well set and life is grand.

Anyway, just a follow-up, and thanks boys for the guidance.

It's lovely to be afloat, swinging on the hook ... still, I confess that
I'd almost like to raise the anchor and take a tour of the area just to
show off my new ground tackle!!!

Definitely, strut your stuff; but first, send me $29.99 and I'll send you a quart of Jill's Super Duper Anchor Polish, guaranteed to keep mud, grass and sand from sticking to your anchor. It will also make your anchor outshine any other anchor in the marina, even the stainless steel anchors. Everyone should have a quart or two of this stuff in their lazarette locker.
 
For a limited time, send a bigger check and we'll include a bottle of Jill's Super Duper Chain Polish. Just because the label is written in Magic Marker, doesn't mean it won't work! And for even more money, you can get a gallon of Jill's Super Duper Rope Polish. Hurry, before the supplies run out.
 
Now, is this where I should put that disclaimer?

How much to have her autograph the bottle?

Jeff, she's been signing them at the point of sale without thinking about charging for the autograph, but thanks for the idea. Maybe she'll see the wisdom in this idea, after all, every dollar helps. Oh, by the way, did I mention that the rope polish also works on snubbers and dock (oops) mooring lines too? Or should that be pier lines, maybe finger pier lines??

Janice,

I have a Rocna 88 KG on my bow (1/2 inch chain) and when I finally learned how to set it, it is amazing how it holds........

Knocking on wood, it has yet to slip... unless I screwed up the setting......
